IIIIIIIIIIIIIIIIIlIIII/llIIIl/II/II! z- III/ll Patented Sept. 8, 1936 PATENT OFFICE DEVICE FOR RECEIVING AND DISCHARG- ING MEASURED QUANTITIES OF LIQUID Rudolf Hebeisen, Wohlen, Aargau, Switzerland Application October '7, 1933, Serial No. 692,597 In Switzerland April 18, 1932 Claims.

The present invention relates to means for receiving and discharging measured quantities of liquid, for instance, a flushing apparatus for sanitary closets. The known flushing .devices for 5 sanitary closets are all provided with a float which acts as the control device. Flushing devices involving the use of a float do not, however, answer modern requirements inasmuch as they frequently get out of order and require almost continuous repair and attendance.

The subject of the present invention is free from these disadvantages and consists substantially in a device for the reception and discharge of a predetermined, but variable quantity of liq- *uid, for instance, water. The liquid is taken from a pressure conduit and may be used for any purpose, more particularly for flushing a sanitary closet.

The improved device according to the invention consists of a completely closed container adapted to receive the liquid direct from a pressure conduit, and provided with a liquid discharge valve which is not controlled by a float,

but is controlled by the liquid within the con- 25 tainer.

One embodiment of the invention is shown by way of example in the accompanying drawing in a sectional elevation.

In the drawing I indicates the liquid discharge .valve which, as previously stated, is not controlled by a float, but is controlled by a quantity of liquid contained in a cylinder 2 communicating with the main liquid container. The liquid to be discharged in predetermined quantities, en- 35 :ters a completely closed main container 4 from a pressure conduit (not shown) through the admission union 3. A baflle 5 is arranged above the point of entry of the liquid, that is, above the union 3, in order to reduce the noise which night 4.0 otherwise be caused by the entering liquid. A valve casing II is fixed to the container, such casing being provided with an interior cylinder 2, preferably cast with the casing in one piece.

reduced portion 21 of the rod'22 and the'passage In'the cylinder 2 works a piston 6 provided with 45 a piston ring I and rigidly connected by a piston rod 8 with the main discharge valve I. The main discharge valve I controlsthe main discharge opening 9 of the container 4. The piston rod 8 is guided in a conical cover ID of the cylin- 50 der 2. Between the cylinder 2 and the wall of the valve casing II is provided a hollow space I2 for the discharge of the liquid from the main container. Below the bottom I3 of the cylinder 2 and at right angles to the axis of the casing I I, 55 a bore I4 is provided in the valve casing II, in

is provided with a packing 2| in order to ensure 10 a tight closing, and is rigidly connected with a rod 22, a spring 24 tending to move the valve against its seat 23. A packing gland 25 serves: for obtaining a tight sliding joint. By means of a lever 26 acting upon the control member I5 .15

and the rod 22, the valve may be moved away from its seat against the action of the spring 24. The liquid which has passed through the passage- I8 into the bore I4 passes when the valve 20 has been moved away from its seat, into an annular 20 space surrounding a reduced portion 21 of the rod 22 and therefrom through a cross bore .28 into the cylinder 2 below the piston. Thepiston is then exposed to the same pressure as the valve I over the main discharge opening 9, but as the 25 piston has a greater area than the area of the Valve I, the piston 6 rises in the cylinder 2 until it reaches a stop 29 formed by the lower edge of the cover. By the movement of the piston 6, the valve I is also lifted through the piston rod 30 8 and the main discharge opening 9 is uncovered. The liquid now descends from the main container between the wall of the valve casing II and the cylinder wall 30, flows around the transverse valve casing 3| and into the discharge union 32. 1

As soon as this discharge has been started, the hand operated lever is released. The rod 22 now returns under the action of the spring 24 into its initial position, and the valve 20 closes the flow of the liquid into the cylinder 2. Atthe same time, the rod 22 uncovers a passage 33 and consequently the water quantity under the piston can flow through the passage 28 around the screw 34 serves for varying the cross section of J the passage 33 and the time within which the water is discharged from below the piston 6. In this manner the quantity of water discharged from-'the'container 4 is regulated. If the cylinder 2 is discharged more slowly, the valve I remains a longer time open and consequently the main container will feed a discharge pipe 35 connected to the discharge union untilthe cylinder is completely emptied. When the discharge of the main container 4 commences, additional water can flow from the pressure pipe into the container. The cross section of the supply pipe should be considerably smaller than the cross section of the discharge.

After the closing of the main valve I, water will fiow from the pressure pipe into the container through the union 3 until the pressure in the container 4 and in the pressure pipes become equal.
